The invention relates to improvements in binders and particularly a binder having improved loose-leaf holding means.

An object of the invention is to provide an improved binder in which the loose leaves, when the binder'is open, shall spread out flat in order to facilitate inspection of or writing on same. 1

Another object is to provide a loose-leaf 1o binder with improved means to facilitate ready insertion or removal of loose-leaf sheets.

Another object is to provide a binder with improved manually operable means for securing or releasing the contents therein.

Another object is to provide an improved article of the character referred to with a receptacleadapted to contain such writing material as a pen and/or a pencil.

Another object is to provide an improved binder with an interchangeable memoranda or calendar pad.

Another object is to provide animproved binder adapted to contain loose-leaf sheets havingextensions thereon, with means for holding said extensions to prevent their be coming torn or crumpled.

The foregoing and such other objects of the invention as will appear hereinafter as the description proceeds, will be more readily understood from a perusal of the following specification, reference being had to the accompanying drawing, in which: f

Fig. 1 is a perspective viewof the improved loose-leaf binder, shown open.

Fig. 2 is a fragmentary plan view ofthe binder.

Fig. 3 is a transverse sectional view of the improved loose-leaf binder, taken on line 83 of Fig. 1.

Fig. 4 is a transverse sectional view through the back of the binder, taken on line 4 1 of Fig. 2. y 7

Fig. 5 is a sectional perspective view of a portion of the back, showing the receptacle therein.

.The improved loose leaf binder preferably includes a rigid back member 11 which may be semi-circular in cross-section, or of any suitable shape, having a chamberhollowed out to provide a space for movable parts and for such writing equipment as may be placed therein. The back 11 preferably is closed at its ends and is provided with a plurality of transverse partitions 12 arranged to divide the chamber therein into a plurality of compartments including those marked 13 and 14,

Suitable oscillatable rock shafts 15 extend longitudinally of the back and are journaled in the partition walls12, one adjacent each side wall of said back, as shown. Ordinary book covers 16 are secured by hinges 17 to the respective side walls of the back 12 and are adapted to fold outwardly therefrom to" provide a substantially flat surface when the binder is open. The chamber portions in the back 11 between each end wall and the ad acent partition wall 12 preferably are closed to provide a finished surface, by a top 'plate 18.

The compartments 13 adjacent the closed end portlons are adapted to contain suitable loose-leaf securing mechanisms Which will be referred to'in detail hereinafter. The intermediate compartment 14 is adapted to contain such writing equipment as it may be desired to place therein, and said, compartment is provided with a suitable cover 19 preferably hingedly mounted upon one of the longtudinal rock shafts 15. A yieldable clamp 21 fixedly secured on the under side of the cover 19 is adapted and arranged to cooperate with the other rock shaft 15 foryieldably securing the cover inclosed position.

If desired, a frame 22 adapted to contain amemoranda pad or calendar 23' may be mounted upon the outwardly disposed face of the cover 19. I

F ixedly secured on each rock shaft 15, and

extending inwardly and upwardly laterally therefrom are a pair, of spaced impaling prongs 24 which are centrally located in the respective compartments13. The impaling prongs 24 are substantially arcuate shaped and each arches over the respective compartment 13 substantially to a point vertically above the longitudinal center of the book back 11. The prongs on each rock shaft are adapted to co-operate with the respective prongs on the other rock shaft to provide a continuous arch over the chamber compartment 13 when said prongs are in closed position.

Suitable sheets of paper 25 are adapted to be held in the improved loose-leaf binder by said prongs 24, said sheets being provided with spaced extensions 26 having apertures 27 therein to receive said prongs. \Vhen the sheets are arranged in the hinder the extensions 26 extend into the respective compartments 13. Extending laterally of the side walls of the back 11 within each compartment 13 are lips 28 arranged to co-operate with the sheet extensions 26 to prevent their becoming mutilated or torn. The provision of sheets having extensions 26 thereon is particularly desirable when using a notebook binder of the improved character, because said sheets will lie flat. upon the covers 16 and the intermediate cut-out portion thereof provides for viewing the memoranda or calendar pad 23 and permits access to the chamber 14 therebeneath.

To provide for opening and closin the impaling prongs 24, each of the rock Shafts 15 has an arm -29 extending at right-angles from one end. The free end of each arm 29 is formed with a suitable bearing portion 31, adapted to extend into and-co-operate with a slot 32 formed in each arm 33 of a crosshead 34. This cross-head has a tapped opening for receiving therethrough an adjusting screw 35 rotatably mounted in the back but held against end-Wise movement. Upon manipulation of the screw 35, the cross-head 34 is moved therealong, thus varying the position of the arms 29 and bearing members 31, to-eifect rocking, in'opposite directions, of the shafts 13. v

Manipulation of the screw 35 is effected by a suitable thumb nut 36 which is fixedly "secured upon the reduced end, 37 of said screw, which inner end projects through the top plate 16 adjacent one end of the back 11. The other end of the screw 35 is journaled in a suitable bracket 38 mounted on the inside face of the back 11.

It can readily be understood that the improvedloose-leaf binder is very eflicient in use and because novel loose-leaf sheets are provided and mounted in a novel manner, a substantially flat writing surface is assured. The improved sheets arealso held within the binder by novel mounting means of a construction which insures their being secured and locked in place. WVhen the impaling prongs are in open position, as shown in dotted lines in Fig. 4, a sufliciently large space is afforded between their opposed ends *to make insertion of new sheets 'very easy.

Although an exemplary form of the loose leaf binder has been shown in the accomanying "drawing and described herein in etail, it is-to be understood that the improved construction may embody such variations in detail structure as will fall with in the spirit of the invention and the scope of the appended claims.
